GROUP 5!!!!!!!!!!!!!!!!!!!!!!!!!!



SARAH~JESS~NICK~HALLE


Hi, this is group 5. We want everyone to know that we all generally enjoy chips, brownies, no homework, and days off of school. We also share a common dislike of dresses.

DAYS LEFT OF SCHOOL: 4 1/2 (not counting weekends and days off, but counting today)




Egg Bio: Gary James Fergison IIII had a hard childhood. His father, Gary James Fergison III, was a caterpillar who lived by the lake at Pocono Valley Resort and was drowned before Gary James Fergison IIII was born. He lives alone in a trailer park with 151 cats, alone, as in he is the only one in the trailer park. He is hidiously disfigured, with a shiny bald head, 3 eyes, and no nose.

Blockhead!!!
Since I am out, I am a blockhead, I have been given the job of being sportswriter... but I am having difficulty thinking of what to write.

Red block, Nick places a yellow block and Halle places a green. The stack grows and it gets more difficult to place the blocks. Halle places a yellow carrot on the stack, clearly making it impossible for Nick to win. He tries anyway and the blocks fall.


Center of Gravity:
  • the average location of the weight of an object
  • in flight, planes rotate on their center of gravity

Lab Report:

Sports and Bonds:


  • Swimming is like ionic bonding because when the swimmer pushes off the wall+swims to the other side it is like one atom ripping an electron off another atom.
  • Basketball is like metallic bonding because in a metallic bond there is alternating positive and negative charges that are like in basketball when one defender is covering one offender.
  • Hockey is like covalent bonding because in a covalent there is two atoms sharing an electron and in hockey there are two teams sharing the puck trying to score.



Interview with an Electron:

Metallic:

  • Substances are good conductors of electric current.
  • There's an attratction of positive ions and free-moving electrons

Ionic

  • There is a transfer of electrons
  • Compounds have a crystal lattice
  • A metal reacts with a none metal

Covalent

  • There's an attraction between nuclei and shared electrons
  • Two or more nonmetals are involved

Observations

NaHCO³ + C27H28Br2O5S

  • when mixed, the solution turns a whitish blue
  • the sodium chloride doesn't dissolve
  • the temperature slightly lowers to 21.1 C
CaCl2 + C27H28Br2O5S

  • the temperature raises to 45.8 C
  • the calcium chloride doesn't dissolve
  • the solution turns a yellowish color
NaHCO3 + CaCl2
+ C27H28Br2O5S

  • when bromothymol blue is added a yellow foam overflows the test tube.
  • the temperature is 27.6 C














Chemical Reactants:

Sodum Bicarbonate- NaHCO3
- white crystalline solid, can also be a powder
- found in mineral springs
- the natural mineral form in nahcolite
- also known as baking soda, or bicarbonate of soda
- reacts with vinegar and water
from:
http://en.wikipedia.org/wiki/Sodium_bicarbonate

Calcium Chloride-CaCL2
- it is highly soluable in water
- a salt and a solid at room temperature
- it is used in cement and can be produced from limestone
- irritant
from: http://en.wikipedia.org/wiki/Calcium_chloride

Water - H2O
- water is the liquid form
- ice is the solid form
- water vapor is the gas form
- covers approximately 71% of earth's surface
from: http://en.wikipedia.org/wiki/Water

Bromothymol Blue- C27H28Br2O5S
- also known as dibromothymolsulfonephthalein
- indicator for weak acids and alkalines
- turns yellow when carbon dioxide is added
- as a neutral is green or blue
from: http://en.wikipedia.org/wiki/Bromothymol_blue
